Old ‘type’ is now T12 but they are still everywhere.
Now the latest is T8 which is more energy efficient and are replacing the T12. Bulb and ballast types need to match.
The fixture ’style’ (2×4 or 8′ or…. ) needs to fit the application

Electronic Ballast, 3 or 4 lamp 2′x4′ lay-in is the most commonly used Lighting fixture (Commercially)

most common is a 2×4 lay in fixture using T-8 tubes and an electronic ballast. Compact flourescent is the best alternative for replacing incandescent lamps.
